Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of transgenic crops and their traits.
Step 2: Detailed Explanation:
Rainbow papaya is resistant to PRSV (Papaya Ringspot Virus).
It was developed by inserting a coat protein gene from PRSV.
It saved the Hawaiian papaya industry from PRSV.
Aphids (B): Not the target.
Fruit rot (C): Not the target.
Delayed fruit ripening (D): Not a trait of Rainbow.
Thus, Rainbow is resistant to PRSV.
Step 3: Final Answer:
Thus, Rainbow papaya is resistant to PRSV, which corresponds to option (A).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?

List-I (Name of the Enzyme) & List-II (Class of the enzyme)
(A). Pyruvate carboxylase & (I). Oxidoreductase
(B). Fumarase & (II). Hydrolase
(C). Phospholipase & (III). Lyase
(D). Nitrogenase & (IV). Ligase
